The results of studies on a curved planform wing are discussed: these studies consist of 3D unsteady CFD analyses. To test the calculation reliability, 2D analyses were carried out on the NACA0012 profile to estimate the buffet boundary. The curved wing configuration allows a notable reduction of the drag and the aeroelastic instability is postponed compared to a conventional swept wing.
